Lets go back to the F Sharp again..and see if there is a connection ......

A Neutron Star in F-sharp

Jonathan E. Grindlay1

Millisecond pulsars are extreme examples of what can happen when stars evolve into neutron stars in compact binary systems. These rotating objects are spun up by accretion of matter from their binary companions, producing luminous X-ray emission, and later become detectable as pulsars with periods of a few milliseconds (1). As a result, these “fast pulsars” may offer some of the best probes to study matter and space in the relativistic regime of strong gravity. On page 1901, Hessels et al (2) report the discovery of pulsar PSR J1748-2446ad in the dense globular cluster Terzan 5 (Ter5-ad). This object, detected with the Green Bank radio Telescope, holds the new record for the fastest spinning neutron star (or indeed any object of stellar mass or larger). Its spin period is only 1.396 ms, even shorter than that of B1937+21 [the first millisecond pulsar discovered (3)] at1.558 ms. With a rotation frequency of 716 Hz, Ter5-ad reaches a new high note for the music of the celestial spheres – between F and F sharp
